Application led January 5, 19,25, Serial No. 645, and in vFrance January 12, 1924.

The present invention' relates to an improved suspension for Vehicles whereby the vehicle frame will be more suitably main- 'tained durin the travel. 54 The vehic e frame is herein connected .with the axles through the medium ot groups of two combined springs which are or the transverse position with respect to '10' the centre line of the vehicle and act in parallel planes.

.In each group, ma be distributed o is rought upon each spring, or the' entire I load is supported byI one of the springs lwhilst the other serves as a shock absorber,

i. e. to brake the oscillations of the Suspended mass when the latter exceeds the position of equilibrium.

rihe appended drawings which are given by way of example show various embodiments of the said invention as applied to motor vehicles. v

Fig. 1 is an end v1ew of ay front axle comprising two combined longitudinal springs. p

Fig. 2 is an elevational view of a rear axle which is also provided with combined longitudinal springs.

Fig. 3 shows a mod ication of the suspension represented in Fig. 2.

linev IV-IV of Fig-4 is a section on the Fi 3.

s shown Fi 1,' 1 represents the front axle having at t a ends the steering wheels 2, these latter the known manner by the coupling bar 3 and with the steering control by the rod 4.

i The vehicle frame 5 rests upon the axle 1 through the medium of groups of springs 6, 7 one of whichA is mountedl above and the other below the said axle' by means of straps 8 and bolts 9.

At the :front part, the'said springs vare simply mounted upon'the pivots 10 are secured to the vehicle frame.

In each group', one of -the said springs serve as a support and the other as a spring will alone support the static load;

o load will Shave its deflection ue to its ,convstruction--so disposed as to assume the inoperative position.

, `The o eration isas lfollows;

The ront branches of the main lates will draw forward the vehicle axle an .sprin sv are alone operative only lyv mounted and occupy the lengthwisey the corresponding loadso that one half the loadbeing connected together in' Owing t0 l lsprings can be designed whose strength inlcondition for an approved suspension. .Whlch the' second spring when 'sub'ected to this.

'spring arranged vertically above the suspenwill balancej the braking efforts when the front brakes are thrown on. The supporting when the vehic e is stationary. The shoc absorbing sprin s`- will only act when the position of equili rium of the vehicle frame is departed from', and they will brake the oscillations of the frame.

Fig. 2 shows like parts'mounted upon the. rear drivingaxle of the vehicle.

The power transmission shaft 12 is so disposed as' to impart its motion to the wheels 13. through the mediumof the differential 14 and theaxle 15. At each end of the latter is mounted a roup of springs 6 and -7 u on which the ve icle frame 5 is caused` to ear by means of the pivots 10 at lthe front part and thev shackles 11 at the rear;

as in the preceding arran ement, these latter will provide for the elongation of the sprin s, whilst'theivots 10 serve to trans mit t e driving an braking stresses.

- In the'arrangement shown in Fi s. 3 and 4, the s rings- 6 and 7 are provide at each 80 end wit the shackles 11 or with'like means connecting them with the vehicle frame. The spring 7 herein disposed below the axle 15 serves as the supporting s ring, whilst the spring 6 serves as the shoc absorber.

Two Acurved angle pieces 16 which are bolted to the corresponding longitudinal of the frame are also disposed above the said shock absorber'so as to serve -as abutments therefor inthe event of a static or a dynamic overload.l The curvature of the said angle'pieces is such that the length of the branches of the spring will be progressivel reduced, whereby the flexibility of the who e suspension system will be diminished. the addition of these surfaces,
